FIELD: cable mounting at building linear erections of local communication networks.
SUBSTANCE: method comprises steps of expanding branch pipes at one side by angle 90 degrees and placing it in opening of lead disc; welding flanges of branch pipes to end surface of lead disc; placing box on said surface and welding through butt of box and disc along contour. Outer diameter of disc exceeds that of box by 10-12 mm. When flange of one branch pipe overlaps flange of other branch pipe at placing branch pipes in openings of disc, cut is made by means of hack saw. Then said cut is completely sealed.
EFFECT: enhanced quality of parts, simplified process for making them, lowered cost of process due to reduced quantity of solder.
